State of the Art Lie Detector Equipment in New Zealand
A polygraph test may seem extreme to some but it is a guaranteed way of establishing the truth. No matter what the issue, if you doubt somebody’s integrity or the answers they have given you, a lie detector test is your solution.
In this page there is information on the state of the art Equipment Lie Detector New Zealand uses, possible questions for the test and accuracy points. If you have any questions that are not covered below don’t hesitate to make contact with your queries.
Industry Leading Equipment
Lie Detector New Zealand use the very latest state of the art computerized equipment; the Lafayette LX5000 Data Acquisition System and associated computer software.
This computerized equipment is linked to the instruments that are attached to the examinee’s body on the outside of his/her clothing. Two pneumographs are used to record breathing, one for the thoracic breathing and one for the abdominal breathing; a cardio cuff to record changes in blood pressure and pulse rate; two finger cuffs to record perspiration activity.
Lie Detector New Zealand also use three separate activity sensors to detect any movements made by the examinee which are primarily associated with countermeasures and deception.
Polygraph Accuracy
The figures relating to the accuracy of the polygraph will vary by a few percentage points depending on the source of the study but generally it is around 96%.
Reference to the term accuracy is misleading. The 96% means that in 96 out 100 tests the results were “deceptive” or “truthful”. It is an erroneous perception that the remaining 4% are errors. They are not errors or inaccuracies, they are simply inconclusive results.
The Key Question Formulation
A key question is one short direct and single question which addresses the issue to be resolved. The only answer required by the examinee is “yes” or “no”.
There are no questions that can confuse the examinee. There are no surprise or trick questions. An examinee will only be asked questions which have been discussed and fulled reviewed with the examiner prior to the onset of any testing.
